ECM

ECM : Description

Performing the following procedure can automatically activate recommunication of ECM and BCM, but only when the ECM is replaced with a new one*.

*: New one means a virgin ECM that has never been energized on-board.

(In this step, initialization procedure by CONSULT-III is not necessary) NOTE

:
• When registering new Key IDs or replacing the ECM that is not brand new, refer to CONSULT-III Operation Manual NATS-IVIS/NVIS.

• If multiple keys are attached to the key holder, separate them before beginning work.

• Distinguish keys with unregistered key IDs from those with registered IDs.

ECM : Work Procedure

1.PERFORM ECM RECOMMUNICATING FUNCTION

If “READ CONFIGURATION” can not be used, use the “WRITE CONFIGURATION - Manual selection” after replacing BCM.

AFTER REPLACEMENT

CAUTION:
• When replacing BCM, you must perform “WRITE CONFIGURATION” with CONSULT-III.

- Complete the procedure of “WRITE CONFIGURATION” in order.

- If you set incorrect “WRITE CONFIGURATION”, incidents might occur.

- Configuration is different for each vehicle model. Confirm configuration of each vehicle model.

• When replacing BCM, perform the system initialization (NATS).

BCM : Work Procedure

1.SAVING VEHICLE SPECIFICATION

CONSULT-III Configuration
